To all whom it may com-em:

. Be it known that; I, DAVID L. SILVER, a citizen of the United States,residing at Clayton, in the county of Gloucester and mprovements 'in'Mop Heads and Detachable Gonnectio'nsThere' A for, oi which'thefollowing is 'a specification, reference being hadtherein'tothe-accompanying drawing.

My nvention relates generally to mop or brus heads, wherein the mopstrands or brush bristles are secured between a plurality of twistedvwires, said wires being bent upon reverse turns and having oppo wires1,v are secured adjacent each other,

"by' means 'of anencircling metallic clampsitel facing ends insubstantial contact.

e invention relates specifically to means for clamping said ends rigidlin position and in substantial contact, andto the-production of meansadapted for.detachable connectionto an operating handle. One of theobjects of .the invention is the provision detachedfrom the ban le tionof pressure at one point only.

i of an element which will' not only provide the necessary. clalnsling1means," but which also co-operates wi e operating handle whereby it maybe automaticall secured to lthe atter by the application 0 pressure ony.

Another object of the invention is the provision of means whereb thehead may be by the app ica- Still another object of the invention is Ithe provision of a] mop or brush handle so constructed and so(Bo-operating with .the head, that either side of the head may be*applied fiat-wise to the work, the handle remaining 'at the sameinclination thereto. Other objects will be apparent from the followingspecifications. s

' In the drawing forming a part of this specification Fi re 1 is a comosite view ,showin the mopcad and the andle separated t erer i a I yFig.2 is a perspective view,of the receiving end of the handle I \L ig.3 is afraginentapy view, partly int section, showing t e han le appliedto'the mo -head;'

it .isibent to clampm p I v lieferring specifically to the drawings,

the invention is here shown as applied to a mop-head A. As hereinbefore;indicated,

the invention is equally a p'licahle to a brush, or an other kind ofead.

. The mopead A: is herein shown as in eluding a sup'portin 'member 1comprising a plurality of twisted wires, a plurality .of'strands offabric being held-between the wires and constituting a tuft which is-ofgreater widththan thickness, rendering it somewhat fiat on each side.

The opposed meeting ends of the twisted mg member 2, which, by diestamping,' is bent around the wires 1 in close contact therewith, andwhich may be rigidly sol-' dered or. brazed thereto, whereby-.rotativeor lateral movement with respect'to the laid between theflanges,transversely of the clamp, and the flanges 14: and 13 aresubjected, to the action of a die which clampsv them totheposition'shown in Fig. 5, the flange 14 extending over the flanges .13,and

this construction part of the metal of the clamp is forced, under highpressure,'1 nto the spirals formed by'the twisted wires, and rotativemovement between the clamp and wires, as well as movement of the clamplongitudinally of the wires, is efiectually the blank Y r the Wiresbeing clamped therebetween. "By

substantial y flat front dicated, the stem 3 tapers from its pointofconnection to the clamp 2, and, near'the outer end thereof, isinteriorl provided with a dog 5', provided with as ank-6,. en-

circledby a coiled spring 7.- Th p ing is neteined in its properpositien by shonl ders'8, projecting on etch side .of the dog'- 5, andby a, ro ection 9,1struck up from the body of t e: stem 3.
